Abstract (en)

[origin: EP1739188A1] Disclosed is a method for measurement of the activity of the homocysteinethiolactone hydrolyzing enzyme in a sample, which method comprises mixing and reacting ³-thiobutyrolactone and the sample in the presence of a cholinesterase inhibitor, and measuring 4-mercaptobutyric acid thereby produced. The method is safe and easy in operation, for it does not use a radioactive substrate, and is free of the influence of other compounds occurring in a sample from the body.
